MCP9808

Microchip Temperature Sensor

Device Details

Device addresses: 24, 25, 26, 27, 28, 29, 30, 31
Address type 7-bit

Registers

configuration

Configuration Register * Address 1 * 16-bytes

The MCP9808 has a 16-bit Configuration register (CONFIG) that allows the user to set various functions for a robust temperature monitoring system. Bits 10 through 0 are used to select the temperature alert output hysteresis, device shutdown or Low-Power mode, temperature boundary and critical temperature lock, and temperature Alert output enable/disable. In addition, Alert output condition (output set for TUPPER and TLOWER temperature boundary or TCRIT only), Alert output status and Alert output polarity and mode (Comparator Output or Interrupt Output mode) are user-configurable.

Fields

#/registers/configuration/limitHysteresis

TUPPER and TLOWER Limit Hysteresis bits

Bits 10:9

Field values

0: 0°C (power-up default)
1: +1.5°C
2: +3.0°C
3: +6.0°C

This bit can not be altered when either of the Lock bits are set (bit 6 and bit 7). This bit can be programmed in Shutdown mode.

#/registers/configuration/shutdownMode

Shutdown Mode bit

Bit 8

Field values

0: Continuous conversion (power-up default)
1: Shutdown (Low-Power mode)

In shutdown, all power-consuming activities are disabled, though all registers can be written to or read. This bit cannot be set to ‘1’ when either of the Lock bits is set (bit 6 and bit 7). However, it can be cleared to ‘0’ for continuous conversion while locked.
